Abstract

A system for determining an actual interferer transmitting an interfering signal comprising first frequency portions of the interfering signal in a predetermined frequency band of a useful signal is provided. The system comprises an antenna module (110) for receiving a transmitted radio signal to obtain a received radio signal comprising second frequency portions of the transmitted radio signal in the predetermined frequency band. Moreover, the system comprises an RF front-end (120) for processing the received radio signal to obtain a preprocessed signal (f). Furthermore, the system comprises a signal demodulator (130) for processing the preprocessed signal (f) to obtain a compressed signal (ŷ). Moreover, the system comprises a signal evaluator (140) for identifying the actual interferer. The signal evaluator (140) is configured to determine for each possible interferer of the plurality of possible interferers coefficient information (x) of said possible interferer based on representation information (Ψ) of said possible interferer and based on processing information (R, H, D), such that the coefficient information (x) of said possible interferer and the representation information (Ψ) of said possible interferer together indicate the preprocessed signal (f), wherein the processing information (R, H, D) and the preprocessed signal (f) together indicate the compressed signal (ŷ). Furthermore, the signal evaluator (140) is configured to determine a possible interferer of the plurality of possible interferers as the actual interferer based on the coefficient information of each of the plurality of possible interferers.
